Matthew Poole and continuators on Revelation 21:12

12 And had a wall great and high , and had twelve gates , and at the gates twelve angels , and names written thereon, which are the names of the twelve tribes of the children of Israel .

That is, this City, by which is meant the Church of God, had

a Wall great and high; Walls are for the Protection and Defence of a place, the higher and greater they are, the greater Defence and Protection they give. By this God is meant, who is often called his Peoples Rock and Defence.

The use of the Gates of a City, are to let persons in and out; the Church is said to have twelve Gates, because of the free liberty of access to the Church while it was Militant, and to signify that the Church in Heaven will be made up of Persons come into it from all parts; or for the greater state and glory of it. Some think, because of the 12 Apostles, who were the first Ministers of the Gospel who admitted Men: into this Church.

Denoting the Guard of Angels about the Church; unless by Angels, Ministers be to be understood, proportioned to the several parts of the Church.

Because as of old, only the 12 Tribes of God's Chosen people Israel, made up the Church in that Period; so only God's Elect and peculiar People, typified by that Israel, come in at the Gates of this Church. It is very observable; how God affects the number of i[illegible: 1 letter] in the affairs of his Church.
